TECHNICAL FIELD

The present invention relates generally to mobile devices and more specifically to a mobile device electronically binding itself to a lost mobile device.

BACKGROUND

Mobile electronic devices are an integral part of modern life. Notebooks, netbooks, tablet computers, smart phones and other portable devices comprise more than half of all computers produced worldwide. People use them to communicate, work, relax, and study. The memory in these devices store large amounts of personal data such as contacts, photographs, videos, authorization information, and much more. Corporate computers also contain official correspondence and documentation, which may include trade secrets.

These mobile electronic devices are often targets for theft or robbery. Criminals can have various objectives: to gain access to a computer's hard drive, to sell the computer, or, rarely, to use it themselves. Portable devices are easily lost due to their size and the fact that they are constantly moved around by the user.

DETAILED DESCRIPTION

Mobile devices or smart phones have become an essential part of our lives. Their use has gone beyond just making phone calls or texting. Nowadays, these smart phones are all-in-one communications, entertainment, social media and networking devices. They also contain a lot of information about us, much of it private. (e.g., contacts, likes/dislikes, notes, ideas, etc.)

The present invention involves other nearby mobile devices to solve the “lost device” problem. A nearby “good Samaritan” phone or mobile device electronically binds itself to a lost device in its vicinity. This can last until such time that the owner of the lost device or other responsible entity (e.g. a mobile operator) accepts responsibility or control over the lost device.

The advantages of this are that the probability of finding a lost device is increased because other mobile devices can now be actively involved. The lost device could, for example, send a message directly to the mobile operator's system but utilizing nearby devices provides for a speedier and more efficient recovery mechanism and an extra protection mechanism.

A detailed description of cloud computing is given in this section to provide a better understanding of the underlying teachings discussed herein.

The present invention will now be described in detail with reference to the Figures.

FIG. 1 depicts a diagram of computing environment 10 in accordance with one embodiment of the present invention. FIG. 1 provides only an illustration of one embodiment and does not imply any limitations with regard to the environments in which different embodiments may be implemented.

In the depicted embodiment, computing environment 10 includes lost device 40, guardian device 50, and mobile operator server 60, interconnected over network 20. Network 20 may be a local area network (LAN), a wide area network (WAN) such as the Internet, the public switched telephone network (PSTN), a mobile data network (e.g., wireless internet provided by a third or fourth generation of mobile phone mobile communication), a private branch exchange (PBX), any combination thereof, or any combination of connections and protocols that will support communications between lost device 40, guardian device 50, and mobile operator server 60 in accordance with embodiments of the invention. Network 20 may include wired, wireless, or fiber optic connections. Computing environment 10 may include additional computing devices, servers, or other devices not shown.

Lost device 40 is a smart phone. In other embodiments, lost device 40 may be a laptop computer, tablet computer, or personal digital assistant (PDA). In general, lost device 40 may be any mobile electronic device or mobile computing system capable of sending and receiving data, and communicating with guardian device 50 and mobile operator server 60 over network 20. Lost device 40 contains contacts Application Programming Interface (API) 80A, location Application Programming Interface (API) 90A, and device recovery program 100A.

Guardian device 50 is a smart phone. In other embodiments, guardian device 50 may be a laptop computer, tablet computer, or personal digital assistant (PDA). In general, guardian device 50 may be any mobile electronic device or mobile computing system capable of sending and receiving data, and communicating with lost device 40 and mobile operator server 60 over network 20. Guardian device 50 contains contacts Application Programming Interface (API) 80B, location Application Programming Interface (API) 90B, and device recovery program 100B.

Lost device 40 and guardian device 50 are at location 70. Location 70 is an area where lost device 40 and guardian device 50 may communicate over personal area network 30. Personal area network (PAN) 30 may be a computer network with a small geographic scope. Computer networks with a small geographic scope range from Near Field Communication (NFC) to Local Area Networks (LANs). A computer network with a small geographic scope typically does not have a connection to the Internet or other remote networks. Personal area network (PAN) can be used for communication among mobile devices themselves (intrapersonal communication), or for connecting to a higher level network (e.g., the Internet). A wireless personal area network (WPAN) is a PAN carried over wireless network technologies such as Bluetooth® or peer-to-peer communications over a wireless LAN (Bluetooth is a registered trademark of Bluetooth SIG, Inc.). In embodiments of the present invention, lost device 40 and guardian device 50 each have the necessary hardware to allow for communication over whatever PAN is used for communication between them (e.g., a Bluetooth radio).

Mobile operator server 60 is a server computer. In other embodiments, mobile operator server 60 may be a management server, a web server, or any other electronic device capable of receiving and sending data. In another embodiment, mobile operator server 60 may represent a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. Mobile operator server 60 contains device recovery server program 110.

Lost device 40, guardian device 50, and mobile operator server 60 may each include components as depicted in further detail with respect to FIG. 4.

Contacts API's 80A and 80B are application programming interfaces that programs can call to retrieve contacts stored on lost device 40 and guardian device 50, respectively. In one embodiment, contacts are stored in a repository on lost device 40 and guardian device 50. The repository contains stored contacts and includes information associated with each contact. The information associated with each contact may include, but is not limited to, the name of a contact, telephone number of the contact, the email address of the contact, and any other information about the contact. In one embodiment, the repository is a repository that may be accessed through contacts API's 80A and 80B. In other embodiments, the repository may be a database such as an Oracle® database or an IBM® DB2® database.

Location API's 90A and 90B are application programming interfaces that programs can call to receive the location of lost device 40 and guardian device 50, respectively. Location API's are application programming interfaces that programs can call to receive the geographic location of a device. The location API receives the geographic location of a device from a Global Positioning System (GPS) receiver (not shown). A GPS receiver is integrated or connected to lost device 40 and/or guardian device 50. A GPS receiver can determine its geographic location and present that geographic location as longitude and latitude coordinates.

In another embodiment, the geographic location of lost device 40 and/or guardian device 50 may be determined by a mobile operator and sent to lost device 40 and/or guardian device 50 to be made available by accessing location API's (e.g., location API's 90A or 90B). A mobile operator may be a cellular telephone carrier if lost device 40 and/or guardian device 50 is a cellular telephone (e.g., smart phone). Cellular networks can determine the geographic location of a cellular telephone by using the radio resource location services protocol. Radio resource location services protocol supports the positioning method, Enhanced Observed Time Difference (E-OTD). E-OTD is based on measurements inside the cellular telephone, where the phone measures the observed time difference of arrival of bursts sent by nearby pairs of base transceiver stations.

Device recovery programs 100A and 100B operate generally to electronically bind guardian devices and lost devices that are near each other (e.g., able to communicate over a personal area network). Device recovery programs 100A and 100B are different instances of the same application on different devices. Device recovery programs 100A and 100B function in different modes depending on the device they are operating on. For example, device recovery program 100A is operating on lost device 40; therefore device recovery program 100A will function in a lost device mode as discussed in further detail with respect to FIG. 2. Device recovery program 100B is operating on guardian device 50; therefore device recovery program 100B will function in a guardian device mode as discussed in further detail with respect to FIG. 3.

Device recovery server program 110 operates generally to provide support functions for device recovery programs 100A and 100B. A support function may include receiving, forwarding, and managing telephone calls or electronic messages (e.g., text messages, email, etc.) between lost device 40, guardian device 50, and other devices (not shown). Another support function may include authentication of devices on a mobile operator's network. In other embodiments, the functionality of device recovery programs 100A and 100B may be done by device recovery server program 110.

An example of a generic scenario is as follows. Jim is cycling and his bike breaks down. Jim accepts a lift from a stranger who drops him in town. When Jim looks for his smart phone (e.g., lost device 40), he realizes he left it in the stranger's car. Jim has no way of finding his smart phone or contacting the stranger. Jim may have not activated his “find my iPhone®” application (or similar application on another device) or the stranger's car may be in an area with no wireless service. Meanwhile, Jim's smart phone is under a seat in the stranger's car. The stranger's smart phone (e.g., guardian device 50) is enabled with an instance of a device recovery program (e.g., device recovery program 100B). The stranger's smart phone detects Jim's smart phone in its vicinity and after finding Jim's smart phone to be lost (activated on Jim's smart phone after a configurable time or when it receives an ‘activate lost phone’ code from a text from Jim), electronically binds itself to Jim's smart phone. The stranger's smart phone retrieves Jim's email address and other details from Jim's smart phone and sends an email with a phone number of the stranger's smart phone and possibly other details (e.g., location). Jim receives the email, rings the stranger and the phone is returned. The stranger's smart phone unbinds from Jim's smart phone.

FIG. 2 depicts a flowchart of the steps of device recovery program 100A (in lost device mode) executing within the computing environment of FIG. 1, for electronically binding guardian devices and lost devices that are near each other, in accordance with one embodiment of the present invention.

Initially, a user of lost device 40 activates and configures device recovery program 100A. The user may configure how device recovery program 100A is to determine that lost device 40 is lost. The many embodiments of how device recovery program 100A may determine lost device 40 is lost will be discussed in reference to decision 200 below. In another embodiment, the user may also configure an optional secure mode for lost device 40 that may be entered in to when device recovery program 100A determines that lost device 40 is lost. The optional secure mode will be discussed in reference to step 210 below. Many other configurable settings will be discussed throughout the discussion of FIG. 2 and FIG. 3. After the user configures the settings of device recovery program 100A, as desired, device recovery program 100A will begin operation.

In decision 200, device recovery program 100A determines whether lost device 40 is lost. In one embodiment, device recovery program 100A monitors the usage of lost device 40 to determine if there has not been any outgoing network activity or user initiated activity such as outgoing text messages, telephone calls, or outgoing internet traffic within a particular time frame. Network activity can be monitored by accessing an API (not shown) that can provide network activity statistics of lost phone 40. For example, the time frame may be one hour, one day, one week, or any other time period. The time frame may begin at the activation of device recovery program 100A. The time frame and its beginning may be configurable by the user of lost device 40. If there has not been any outgoing network activity or user initiated activity within the particular time frame, device recovery program 100A determines that lost device 40 is lost.

In another embodiment, device recovery program 100A monitors the geographic location of lost device 40 to determine if lost device 40 is in an unusual geographic location. Device recovery program 100A calls location API 90A of lost device 40 for the geographic location of lost device 40. Location API 90A receives the geographic location of lost device 40 from a GPS receiver integrated with lost device 40. A GPS receiver can determine its geographic location and present that location as longitude and latitude coordinates. Device recovery program 100A compares the geographic location of lost phone 40 to a plurality of geographic locations previously stored on lost device 40. For example, the plurality of geographic locations previously stored on lost device 40 may have been entered manually by the user of lost device 40 at setup or automatically by software on lost device 40 that constantly monitored the geographic location of lost device 40 during normal operation. If the geographic location of lost device 40 retrieved by device recovery program 100A does not match any of the plurality of geographic locations previously stored on lost device 40, device recovery program 100A determines that lost device 40 is lost.

In yet another embodiment, device recovery program 100A monitors for the receipt of a text message from the user of lost device 40 operating another device or a text message from another known source. The text message must include a code to indicate to device recovery program 100A that lost device 40 is now lost. In one embodiment, the code may be a string of characters entered in the body of the text message received. The code may be preconfigured by the user of lost device 40 at setup. If a text message received contains the code to indicate that lost device 40 is now lost, device recovery program 100A determines that lost device 40 is lost.

In other circumstances, when a device is lost, that device might not have the function to say “I′m lost” or might not yet consider itself lost. The user of that device might engage one or more “good Samaritan” devices to be on the lookout for the lost device and report the lost device if/when it is encountered. Equally, before a device is lost, the user of that device might engage some “good Samaritan” devices to “keep a look out for” the device that may be more likely to be lost in the future. At some later time the user might ask the “good Samaritans” if/where they last encountered the now lost device. Additionally, the “good Samaritans”, rather than each reporting their individual experience of the lost device in this regard, might confer and return a consolidated answer to the enquiring user. Further, the relationship of the “good Samaritans” to the lost (or to be lost) device might be authenticated with the mobile operator, and the “good Samaritan” devices might co-operate with the mobile operator in this regard such that when the user inquires, they ask the mobile operator before reporting the consolidated answer to the user (i.e. it may be that the mobile operator has better info in some cases).

If device recovery program 100A determines that lost device 40 is lost (decision 200, yes branch), device recovery program 100A proceeds to step 210. If device recovery program 100A determines that lost device 40 is not lost (decision 200, no branch), device recovery program 100A ends. In another embodiment, if device recovery program 100A determines that lost device 40 is not lost (decision 200, no branch), device recovery program 100A returns to decision 200.

In step 210, device recovery program 100A changes the mode of lost device 40 to a secure mode. In one embodiment, device recovery program 100A sends an indication to the operating system of lost phone 40 to activate its security features. The security features may include screen-locking which requires a personal identification number (PIN) or password to unlock, blocking access to stored data on lost phone 40, and/or restricting connectivity (Bluetooth, Universal Serial Bus, network). The restrictions relating to stored data and connectivity would not hinder function of device recovery program 100A.

In step 220, device recovery program 100A makes lost device 40 discoverable to guardian device 50. In one embodiment, device recovery program 100A activates the Bluetooth capabilities of lost device 40. For example, device recovery program 100A sends an indication, using a Bluetooth API of lost device 40, to activate the Bluetooth capabilities of lost device 40 and to put lost device 40 in to “discoverable mode.” In other embodiments, device recovery program 100A causes lost device 40 to join any available personal area network such as personal area network 30. For example, if personal area network 30 is a WPAN (e.g., wireless LAN), device recovery program 100A sends an indication, using a wireless network API of lost device 40, to activate a wireless network antenna of lost device 40 and to join the available wireless network.

In step 230, device recovery program 100A receives a request for lost device 40 to electronically bind with guardian device 50 over PAN 30. In one embodiment, device recovery program 100A receives a request to “pair” lost device 40 with guardian device 50 from device recovery program 100B of guardian device 50 over PAN 30. In this embodiment, guardian device 50 must also be Bluetooth enabled and in “discoverable mode.” In another embodiment, if lost device 40 and guardian device 50 are both within range to join the same WPAN (e.g., wireless LAN), device recovery program 100A receives a request to create a peer-to-peer connection from device recovery program 100B of guardian device 50.

In step 240, device recovery program 100A electronically binds lost device 40 with guardian device 50 over PAN 30. In one embodiment, device recovery program 100A “pairs” lost device 40 with guardian device 50 such that device recovery programs 100A and 100B can communicate using Bluetooth protocols. In this embodiment, “pairing” may occur using a known method of “pairing” that does not require user interaction with lost device 40, such as Secure Simple Pairing (SSP). Other methods of “pairing” may utilize the connections between lost device 40 and mobile operator server 60 and guardian device 50 and mobile operator server 60 to exchange authentication tokens or keys as needed.

In another embodiment, if lost device 40 and guardian device 50 are both within range to join the same WPAN (e.g., wireless LAN), device recovery program 100A accepts the request to create a peer-to-peer connection from device recovery program 100B of guardian device 50 such that device recovery programs 100A and 100B can communicate. In other embodiments, lost device 40 and guardian device 50 may be electronically bound such that device recovery programs 100A and 100B can communicate utilizing any known protocols or connections over a WPAN.

In step 250, device recovery program 100A sends information to guardian device 50. In one embodiment, device recovery program 100A receives a request from device recovery program 100B over PAN 30 for information relating to lost device 40. In response to receiving the request from device recovery program 100B, device recovery program 100A sends the information relating to lost device 40 to device recovery program 100B of PAN 30. In order for device recovery program 100A to respond to the request from device recovery program 100B, device recovery program 100A can call various APIs on lost device 40 to obtain the information relating to lost device 40. For example, device recovery program 100A can call contacts API 80A to retrieve the name and contact information of the user of lost device 40 including other contact numbers or email addresses. Device recovery program 100A can call location API 90A to determine where lost device 40 was lost during operation of step 200 described above.

In another embodiment, device recovery program 100A receives a request from device recovery server program 110 over network 20 for information relating to lost device 40. The mobile operator may use information previously configured by the user of lost device 40 while accessing device recovery server program 110 on the mobile operator's system instead of retrieving new information from lost phone 40, itself.

For example, information relating to lost device 40 may include, but is not limited to: the name and contact information of the user of lost device 40 including other contact numbers or email addresses; how long lost device 40 has been lost; where lost device 40 was lost; value of any reward offered for recovery of lost device 40 (this could be preset during the configuration of device recovery program 100A).

In step 260, device recovery program 100A receives an indication to unbind lost device 40 from guardian device 50. In one embodiment, after data is exchanged between device recovery programs 100A and 100B and lost device 40 is returned to its user, device recovery program 100A receives an indication from device recovery program 100B over PAN 30 indicating that lost device 40 is no longer lost. In another embodiment, device recovery program 100A must also receive an indication from the user that lost device 40 is no longer lost. For example, if the secure mode entered in to in step 210 includes screen locking, the entry of the required personal identification number or password to unlock the screen would also disable the lost device status. In other embodiments, device recovery program 100A may only have to receive an indication from the user that lost device 40 is no longer lost.

In step 270, after receiving the indication to unbind lost device 40 from guardian device 50, device recovery program 100A unbinds lost device 40 from guardian device 50. In one embodiment, if lost device 40 and guardian device 50 are “paired” such that device recovery programs 100A and 100B can communicate using Bluetooth protocols, device recovery program 100A removes guardian device 50 as a “paired” device. In another embodiment, if lost device 40 and guardian device 50 are both within range to join the same WPAN (e.g., wireless LAN) such that device recovery programs 100A and 100B can communicate, device recovery program 100A may send an indication, using a wireless network API of lost device 40, to deactivate the wireless network antenna of lost device 40 or to disconnect from the available wireless network.

FIG. 3 depicts a flowchart of the steps of device recovery program 100B (in guardian device mode) executing within the computing environment of FIG. 1, for electronically binding guardian devices and lost devices that are near each other, in accordance with one embodiment of the present invention.

Initially, a user of guardian device 50 activates and configures device recovery program 100B. The user may configure how device recovery program 100B is to operate when communicating with lost device 40 or any other device that is lost. After the user configures the settings of device recovery program 100B, as desired, device recovery program 100B will begin operation.

In step 300, device recovery program 100B scans for devices nearby guardian device 50. In one embodiment, device recovery program 100B makes guardian device 50 discoverable to lost device 40. In one embodiment, device recovery program 100B activates the Bluetooth capabilities of guardian device 50. For example, device recovery program 100B sends an indication, using a Bluetooth API of guardian device 50, to activate the Bluetooth capabilities of guardian device 50 and to put guardian device 50 in to “discoverable mode.” Bluetooth devices that are set on “discoverable mode” have the ability to search for and locate each other, so long as they remain within range. In other embodiments, device recovery program 100B causes guardian device 50 to join any available personal area network such as personal area network 30. For example, if personal area network 30 is a WPAN (e.g., wireless LAN), device recovery program 100B sends an indication, using a wireless network API of guardian device 50, to activate a wireless network antenna of guardian device 50 and to join the available wireless network. In other embodiments, device recovery program 100A scans for devices nearby lost device 40.

In decision 310, device recovery program 100B determines if any devices nearby guardian device 50 have been detected. In one embodiment, device recovery program 100B sends an indication to the Bluetooth API of guardian device 50 to perform an inquiry to find other Bluetooth enabled devices to connect to. Any device in “discoverable mode” can be configured to respond to such inquiries. In another embodiment, once guardian device 50 joins the available wireless network, device recovery program 100B looks for other devices joined to the same network.

If device recovery program 100B determines that no devices nearby guardian device 50 have been detected (decision 310, no branch), device recovery program 100B returns to step 300. If device recovery program 100B determines that one or more devices nearby guardian device 50 have been detected (decision 310, yes branch, device recovery program 100B proceeds to decision 320.

In decision 320, device recovery program 100B determines if any of the one or more detected devices nearby guardian device 50 are lost. In one embodiment, device recovery program 100B sends an inquiry to device recovery program 100A on lost device 40 over PAN 30 to determine whether lost device 40 is lost. If device recovery program 100A on lost device 40 has determined that lost device 40 is lost, as described in reference to decision 200 above, device recovery program 100A will respond to the inquiry from device recovery program 100B and the response will indicate that lost device 40 is lost.

In another embodiment, if lost device 40 is lost but does not have the function to say “I'm lost” or might not yet consider itself lost, the user of lost device 40 may engage one or more guardian devices to be on the look out for lost device 40. For example, the user of lost device 40 may use another computing device to send an indication to be on the look out for lost device 40 to device recovery server program 110. The mobile operator may then send the indication over network 20 to all other devices with an instance of device recovery program 100B running on them. If device recovery program 100B determines that lost device 40 has been detected then the device recovery program 100B will determine that lost device 40 is lost based on the received indication from device recovery server program 110.

In some embodiments, decision 320 may take place after step 330 depending on the protocol used to electronically bind lost device 40 and guardian device 50. For example, if the devices will be bound by using Bluetooth protocols, the inquiry of whether lost device 40 is lost will have to take place after the devices are connected by the Bluetooth protocol.

If device recovery program 100B determines that determines that none of the one or more detected devices nearby guardian device 50 are lost (decision 320, no branch), device recovery program 100B returns to step 300. If device recovery program 100B determines that at least one of the one or more detected devices nearby guardian device 50 are lost (decision 320, yes branch, device recovery program 100B proceeds to step 330.

In step 330, device recovery program 100B electronically binds guardian device 50 to the one detected device nearby guardian device 50 that is lost (e.g., lost device 40). Device recovery program 100B sends a request for lost device 40 to electronically bind with guardian device 50 over PAN 30. In one embodiment, device recovery program 100B sends a request to “pair” lost device 40 with guardian device 50 to device recovery program 100A of lost device 40 over PAN 30. In this embodiment, lost device 40 must also be Bluetooth enabled and in “discoverable mode.” In another embodiment, if lost device 40 and guardian device 50 are both within range to join the same WPAN (e.g., wireless LAN), device recovery program 100B sends a request to create a peer-to-peer connection to device recovery program 100A of lost device 40. Different embodiments regarding electronically binding lost device 40 with guardian device 50 over PAN 30 are discussed in reference to step 240 above.

In step 340, device recovery program 100B obtains information relating to lost device 40 (e.g., the one detected device nearby guardian device 50 that is lost). In one embodiment, device recovery program 100B sends a request to device recovery program 100A over PAN 30 to retrieve information relating to lost device 40. In another embodiment, device recovery program 100B sends a request to device recovery server program 110 over network 20 to retrieve information relating to lost device 40. The mobile operator may use information previously configured by the user of lost device 40 while accessing device recovery server program 110 on the mobile operator's system to respond to the request and/or the mobile operator may retrieve new information from lost phone 40, itself.

For example, information relating to lost device 40 may include, but is not limited to: the name and contact information of the user of lost device 40 including other contact numbers or email addresses; how long lost device 40 has been lost; where lost device 40 was lost; value of any reward offered for recovery of lost device 40 (this could be preset during the configuration of device recovery program 100A). In order for device recovery program 100A to respond to the request from device recovery program 100B, device recovery program 100A can call various APIs on lost device 40 to obtain the information relating to lost device 40. For example, device recovery program 100A can call contacts API 80A to retrieve the name and contact information of the user of lost device 40 including other contact numbers or email addresses. Device recovery program 100A can call location API 90A to determine where lost device 40 was lost during operation of step 200 described above.

In step 350, device recovery program 100B sends the information relating to the one detected device nearby guardian device 50 that is lost (e.g., lost device 40) to a designated party. In one embodiment, device recovery program 100B queries device recovery program 100A for the designated party. In other embodiments, the designated party is retrieved in step 340. For example, the designated party may be the user of lost device 40 at the users other contact numbers or email addresses. In other examples, the designated party may be another specified friend of the user, the mobile operator, the police, or a third party security system.

In yet another example, a designated party may not have been set by the user during configuration of device recovery program 100A. In such a case, device recovery program 100A may send all or a subset of contacts to device recovery program 100B. Device recovery program 100B, upon receipt of all the contacts or a subset of contacts will compare the contact list on guardian device 50 (accessed through contacts API 80B) with the received contacts for matches. If device recovery program 100B finds any matches it can prioritize who to contact based on this match.

In one embodiment, if the designated party can be reached electronically (e.g., by text message or email), device recovery program 100B sends the information relating to the one detected device nearby guardian device 50 that is lost (e.g., lost device 40) directly to the designated party. In another embodiment, if the designated party can not be reached electronically (e.g., by text message or email), device recovery program 100B alerts the user of guardian device 50 so that the user may contact the designated party.

In other embodiments, if lost device 40 is not lost but the user of lost device 40 has engaged multiple guardian devices to be on the look out for lost device 40; the multiple guardian devices may coordinate a response to a designated party. In one example, the first guardian device to bind to lost device 40 will receive the information relating to lost device 40 from each subsequent guardian device to bind to lost device 40 and obtain information relating to lost device 40. The information relating to lost device 40 obtained from subsequent guardian devices may included more up to date location information that may aid in finding lost device 40. In another example, each guardian device to bind to lost device 40 may send the information relating to lost device 40 to device recovery server program 110 over network 20.

In step 360, device recovery program 100B receives an indication to unbind guardian device 50 from lost device 40. In one embodiment, after lost device 40 is returned to its user, device recovery program 100B receives an indication from the user of guardian device 50 indicating that lost device 40 is no longer lost. The user may use a user interface to device recovery program 100B to indicate that lost device 40 is no longer lost. In another embodiment, device recovery program 100B must also receive an indication from device recovery program 100A indicating that lost device 40 is no longer lost. Device recovery program 100A may determine that lost device 40 is no longer lost as describe in reference to step 250 above. In other embodiments, device recovery program 100B may only have to receive an indication from the user of guardian device 50 that lost device 40 is no longer lost.

In step 370, after receiving the indication to unbind guardian device 50 from lost device 40, device recovery program 100B unbinds guardian device 50 from lost device 40. In one embodiment, if lost device 40 and guardian device 50 are “paired” such that device recovery programs 100A and 100B can communicate using Bluetooth protocols, device recovery program 100B removes lost device 40 as a “paired” device. In another embodiment, if lost device 40 and guardian device 50 are both within range to join the same WPAN (e.g., wireless LAN) such that device recovery programs 100A and 100B can communicate, device recovery program 100B may send an indication, using a wireless network API of guardian device 50, to deactivate the wireless network antenna of guardian device 50 or to disconnect from the available wireless network. After device recovery program 100B completes step 370 it returns to step 300.
